movement, of head and eye). The number of correct 

 inferences continued relatively high, even after the dis- 

 tance between the papers was decreased tenfold, — as 

 will be seen from the following table:

Beginning with an angle of i' (distance between the 

 centers of two neighboring papers = 2 mm.), the sub- 

 ject was unable to focus, with sufficient steadiness of 

 vision, upon one paper alone, and the movements, for that 

 reason, ceased to manifest themselves. Comparing the 

 results obtained in the case of this subject with those 

 obtained from two others, whose reactions had remained 

 normal, B. and Miss St., we find that with them there 

 were only 53% correct inferences in both cases (based 

 each upon 200 tests), when the angle was 5'. In my 

 errors, too, I often shot wider of the mark. In another 

 series of 200 tests, in which Miss St. " merely thought 

 of the places ", I had a percentage of 56% correct infer- 

 ences, and my errors did not become any coarser. Miss 

 St. believed this a case of true telepathy, but I had been 

 guided in my judgments entirely by her unwittingly 

 made movements — or rather the direction — of her eyes. 

 The magnitude of these movements bore a constant rela- 

 tionship to the distance between papers as it was con- 

 ceived by the subject. 



Reviewing the experiments discussed in this chapter, 

 we find that the same kind of movements and postures,
